Description

The automatic safety visor of argon arc welding machine

Technical field

This utility model relates to the employed safety visor of a kind of electric welder's welding work pieces, is used to protect eyes, not injured by arc light; especially in the time of discerning electric welding machine work, screening glass is closed automatically, the protection eyes; when stopping to weld, the automatic safety visor of the argon arc welding machine that screening glass is opened automatically.

Background technology

At present, known electric arc welding light shield is with cover body, mating plate, clamp is fixed together and makes, divide hand-held and be fixed on last two kinds, because mating plate resistance photosensitiveness is strong, under daylight or light, people's eyes can not pass through mating plate, see welding work pieces clearly, weld after can only moving light shield or manual unlocking screening glass by hands, in the time of welding, mobile again light shield or manual-lock mating plate, eyes are seen welding work pieces by mating plate, have increased workload like this, easy again false judgment, can not in time open or close mating plate, can accurately not see welding work pieces and arc light, wound eyes easily.

Summary of the invention

Can only be in order to overcome existing arc light cover by manually; can not be accurate, correct open or close mating plate; can not protect eyes well; be unfavorable for improving the shortcoming of welding accuracy, this utility model provides a kind of argon arc welding machine automatic safety visor, and this utility model can not only automatically be judged the electric welding machine starting the arc or not have the starting the arc; thereby opening or closing of control mating plate; thereby the protection eyes, and can accurately welding work pieces, and needn't manually control mating plate.During welding work pieces, a hands is taken weld handle plier like this, and a hands can be held up workpiece, increases labour efficiency.

The technical scheme that technical problem adopted that this utility model solves is:

The automatic safety visor of argon arc welding machine, face shield is worn over head, it is characterized in that: automatic catch arc mechanism is arranged on face shield 13, automatic catch arc mechanism comprises: motor M is fixed on the face shield, the outside of the axle 1 of motor M is with gear 2, gear 2 and tooth bar 3 engagements, the fixedly connected screening glass frame 5 in tooth bar 3 lower ends, a slice colour light filter sheet glass is installed in the screening glass frame 5, the dual-side fixed block 6 of screening glass frame 5, the dual-side of screening glass frame 5 is with chute 4, and fixed strip 7 is chute 4 fixedly, and installing hole 8 is arranged on the fixed strip 7, screw passes installing hole 8 fixed strip 7 is fixed on the face shield, it is motionless that planar transparent instrument bezel 9 is installed in the place ahead of screening glass frame 5, and motor M connects K switch 1 back and connects power supply in the argon arc welding machine 12, and spring 10 connects screening glass frame 5 and last fixed legs 14.

The automatic safety visor of described argon arc welding machine is characterized in that: K switch 1 and argon arc welding machine 12 original K switch 2 are installed in the same shell, become one two logical microswitch, and K switch 1 and K switch 2 are gang switch, and K switch 1 is opened in advance than K switch 2; Two wire C, the D of the connection motor M on the automatic safety visor of argon arc welding machine inserts on the electrode holder on power supply A, the B that draws in the argon arc welding machine 12, and K switch 1 is positioned on power supply A or the B, and this supply voltage is equal to or less than 36V.

Principle: in the time of welding, K switch 1 presses button, motor M is just changeed, and axle 1 clockwise rotates, and gear 2 clockwise rotates simultaneously, driving tooth bar 3 moves down, screening glass frame 5 moves down, and blocks the planar transparent instrument bezel 9 that is installed on the face shield, at this moment, press argon arc welding machine 12 original K switch 2, the welding of beginning argon arc.After the argon arc welding is finished, close argon arc welding machine 12 original K switch 2 and K switch 1, argon arc welding machine 12 stops welding, and motor M outage is not simultaneously worked.The pulling force of spring 10 makes on the screening glass frame 5 and moves, and leaves planar transparent instrument bezel 9, and human eye promptly can be seen the outside by planar transparent instrument bezel 9.

The beneficial effects of the utility model are: can automatic mobile screening glass frames 5, needn't use another manual activity mating plate, and effectively protect eyes not injured by arc light.Improve labour efficiency, improve welding quality, simple in structure.
